Rupert — the 42-year-old Snow White and the Hunstman director who was rumored to have had a fling with Kristen last summer — has reportedly been texting and emailing Kristen ever since his wife, Liberty, left him last month.

“Rupert’s reached out to Kristen, but she doesn’t want anything to do with him,” says a source. “He texted her a number of times after Liberty filed for divorce, however Kristen didn’t respond."

“In truth, she regrets ever getting involved with Rupert because of how much it hurt Robert and the amount of public backlash she was subjected to," the source continues.

Kristen apparently doesn't know exactly where things stand with her and Rob, but Rupert doesn't have a chance either way.

“Kristen doesn’t really know what’s going on with her and Robert at the moment, and she’s been left in limbo," according to the insider. "Ideally, she would like things to go back to how they once were, but that’s proving a lot more difficult than she imagined."

"But when it comes to Rupert, that ship has sailed,” the source adds.

Thank goodness! We all know that Rob and Kristen belong together. Take a hike, Rupert!
